Yeah you may need some super high tech mic to pick up the differences but here it is
I definitely think for someone with a really really loud head it would quiet it down some. I could definitely hear a difference while driving. No more choppy rhythm when hood liner is off. Even in my 500hp mk7 the engine sounds like stock unless I start getting into boost
So are you happy with the Cerma treatment? Was your oil hot hot when you added it and did you then drive at least 50 miles?
